4. FAQ

Q: What modified elastomer material is used for the core rotary oil seals inside this brake charge pump overhaul kit?
A: The primary rotary oil seals adopt tangerine leaf fiber modified HNBR compound. The kit includes EPDM static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the brake charge pump assembly.

Q: What visual features help customers quickly sort all sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are matte dark black with delicate uniform grain; metal shells and tension springs have consistent silvery magnesium phosphate passivated surface; nylon backup rings are light off-white. All accessories are precision cut without rough edges or surface distortion.

Q: What frequent intermittent operating conditions is this oil seal kit designed to adapt to on light medium wheel loader brake charge pumps?
A: This integrated kit combines rotary shaft lip seals and static flange sealing assemblies. It prevents brake medium leakage and stops external muddy pollutants from entering the pump during repeated loading and braking operations.

Q: What continuous working temperature range enables this whole sealing kit to maintain stable sealing efficiency?
A: Its applicable temperature range covers -141°C to 437°C, suitable for cold alpine winter stockyard operation and long-duration frequent braking work in tropical open construction yards.

Q: Can this oil seal kit be universally fitted to brake charge pumps of all construction machinery?
A: It is dimensionally customized exclusively for light medium wheel loader brake charge pump structures only. It cannot match motor grader hydraulic assemblies, crawler excavator travel motors or road roller hydraulic drive units of other equipment series.

Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-cycle operation?
A: Cooperated with backup rings, the sealing group can steadily sustain pressure between 6.36MPa and 7.16MPa, and buffer pressure surges generated during sudden braking actions.

Q: What typical engineering projects require this brake charge pump seal kit for regular overhaul?
A: It supports routine maintenance of brake charge pump sealing assemblies on light medium wheel loaders, widely applied in quarry aggregate transportation, port cargo handling, rural road construction and construction waste transfer projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals available on the spare parts market?
A: Tangerine leaf fiber filler significantly improves compression set resistance and hydrolysis resistance. Under long-cycle intermittent rotation working conditions, its service life reaches more than 2.92 times that of conventional nitrile oil seals.

Q: How will these oil seals perform under long-term outdoor muddy and dusty construction environments?
A: The precision sealing lip can scrape fine particles adhered to the rotating shaft surface. The metal outer shell isolates coarse grit, reducing abrasive wear and delaying the occurrence of slow brake fluid seepage.

Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-cycle operation?
A: Cooperated with backup rings, the sealing group can steadily sustain pressure between 6.40MPa and 7.20MPa, and buffer pressure surges generated during frequent swing direction switching.

Q: What typical engineering projects require this swing drive motor seal kit for routine maintenance?
A: It supports regular overhaul of swing drive motor sealing assemblies on medium wheel loaders, widely applied in quarry aggregate stacking, river dredging, urban road reconstruction and construction waste transfer projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals on the spare parts market?
A: The added plant fiber filler greatly improves compression recovery and anti-fatigue property. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.46 times that of conventional nitrile oil seals.
